I firmly believe that science is life, especially to a kid. IMHO: Kiddos are naturally prone to curiosity about their surroundings, and one does not need to go out in search of fancy science courses to experience what the world has to offer. We just follow their natural line of questioning and curiosity and BAM: We are thrust into the middle of the wonderful world of biology (Mommy, why do bees drink from our hummingbird feeder?), geology (What happens when I break this rock apart?), anatomy (When I go to sleep, does my heart go to sleep too?), botany (Why is that plant alive after the flower on it died?), astronomy (If the Earth goes around the Sun, what does the Moon do?), physics (If I throw this ball on the roof, will it always come back down?), etc, etc, etc.
That said, we will occasionally do “experiments” in the kitchen to test certain theories or find out answers for ourselves. One day, we lined up a bunch of small household objects and theorized (and then saw) which would sink or float in a bucket of water. We have filled bottles with water and dish soap to create colorful bubbles. We have combined oil with colored water in a bottle to simulate waves. We have combined test tubes of colored water to make new colors. We have cleaned old pennies in lemon juice. We have grown a few types of plants, as well. And I STILL maintain that every cooking project is a bit of math, science and history all rolled into a delicious outcome.
Our latest “scientific” conversations have revolved around plants and they way they grow. This is largely due to my current attempt to keep a handful of herbs and potted plants alive on the back patio (the jury is still out on whether or not they’ll survive…). But we stuck two pieces of celery into colored water and watched the way the water moved through the plant over the course of a few days. Simple, but super interesting to the kids. They were mildly disappointed when I wouldn’t let them EAT the colored celery at the end, though. Perhaps it’s time for an experiment on the perils of food coloring.
